Hand made in our New Hampshire studios, Derek
Marshall Lighting is unique in the lighting world. Quality beyond question, designs without parallel. Please take a look and judge for
yourself.

Yes, you can buy American made
lighting that outperforms imports in both quality of design, materials
and engineering. You won't find us at the big box stores; everything you
see is made by us to your order, usually in less than one week.

What are your sconces made from?
We use a variety of materials for our sconces. The ceramic body is a
proprietary formula we have developed which has a special
micro-crystal component for great strength with light weight. Other
sconces are made from American art glass, surely the finest such glass
produced in the world today. Finally we have the wrought iron sconces
by David Little with art glass lenses. Click
here for more data.

Most
of our finishes are interchangeable, so if you see a sconce but do not
see it in the finish you would like, please ask for it. Most of the
art glass is interchangeable as well. We also do custom finishes and
custom glass. Ask us, we will be happy to see what we can do. For the
most part, there is no additional charge for changing the finish. We
can also wire for any country in the world and also provide 277 volt
lighting for commercial use.

ADA
stands for American with Disabilities Act. It is a sweeping bit of
legislation enacted in 1991, designed to ensure that people with handicaps are not
excluded from public spaces.
Specifically,
section 4.4 of theADAstates that ”objects
projecting from walls with theirleading
edges between 27 inches and80
inches (2’4” to 6’8”) above the finishedfloor
shall protrude no more than fourinches
into walks, halls, corridors, passage-ways
or aisles.“ It
is a fact that the ADA lighting requirements gave birth to some
unlovely designs. Our job has been to design lighting fixtures that
meet the ADA requirements and yet compromise nothing in terms of
quality of design.
Indeed, this is actually a good size for even non-ADA applications such as
home residences. All our sconces that meet ADA requirements (most do)
are labeled ADA in the catalog.

Underwriters
Laboratories, Inc. is a private, not-for-profit corporation involved
in the safety testing of many products made in this country and around
the world. They maintain a series of standards regarding the safe
manufacturing of many different products. We hold certification for
both table lamps and wall fixtures. To attain this certification, we
had to meet stringent requirements in our materials and method of
manufacture of these products. We pay an annual fee for this and are
inspected at least four times a year to assure compliance. All our
sconces and pendant lights carry a UL label, your assurance that they are
sound and well made from a structural and engineering aspect.

Our
sconces are all rated to a UL standard for “damp location”. This
specifically means they can be used in any interior setting, including
the bathrooms, and they may be used out doors under cover. They are
not designed to take direct rain impingement.

This
is largely a matter of personal taste with a dependence on room
height. Generally speaking, they should be no lower than above average
eye height so that no on can see the bulb in the mounted sconce. This
generally puts the mounting center of the sconce at something like six
and one half feet (80 inches). Higher than this is fine provided that
the ceiling is not too close. Again, generally speaking, you should
have at least a foot above the sconce of free space.Make a rough cut out of the sconce in cardboard, using the
dimensions given in the catalog, and try out for yourself where they
look the best

There
are several factors to consider. First, the glass and glass fronted
sconces will throw more direct light than the ceramic opaque sconces
which are either up-light or up-down lights. Second, the wattage of
the bulb makes a difference. Most of our sconces are rated up to 100
watts for the single bulb versions. Of course, you can substitue a
screw-based compact fluorescent lamp (CFL) which for a given wattage
will give about four times that light of the incandescnt version.
Currently there are varieties of CFLs that go all the way up into 40
watts, or about the light output of a 150 watt incandescent bulb.
Another consideration is the height, color and texture of the ceiling.
In general, a wall sconce should be considered as an ambient light
source. This is an indirect illumination in a room which provides
enough light for general activities not requiring accute vision.
Reading, writing, hand work and such activities require task lighting,
an intense and close light source which may be a table lamp or some
kind of directional light on a flexible arm.Ambient lighting is good for any room, hallway, dining areas,
bathrooms, etc. Task lighting is portable and should be added where
necessary.

We
will be happy to quote prices for any custom work. However, the cost
of tooling up for a new sconce is not insignificant, and may be
prohibitive for just a few sconces. If you are in need of twenty or
more, the cost of a new design may be amortized reasonably across such
an order.

As
stated above, our sconces are rated for “damp location only” and
as such can only be used outdoors where they will be under cover. This
is a UL designation and its application is up to the buyer. Obviously,
there are places in the world where direct rain impingement is not
really a consideration.

Halogen, fluorescent
and LED bulbs have their uses and liabilities. It is
possible to “hard-wire” a sconce to use either one of these type
of bulbs. However, in our opinion, it is much more useful and
economical, to buy these bulb types in their standard
screw-base configuration, readily available at most hardware stores.
These can then be used in just about all our sconces.
Halogen, a particular type of
incandescent bulb, gives a whiter light than
standard incandescent and may be easily dimmed. Compact
fluorescent lamps (CFLs) are available in many different wattages and
as they can be screwed into a standard base bulb holder, the wattage
may be changed at will. This is not true of hard-wired fluorescents.
Fluorescent lamps do not put out a smooth color curve, unlike the
halogen and standard incandescent. This can result in some color
shifts which may or may not be significant to the viewer. Generally
speaking, CFLs cannot be dimmed. LED bulbs are in their infancy.

This
is a frequent question without an easy answer. There are several
variables which go into the equation which include: a. What is
the height to the ceiling? b. How much light is needed (both in
reflected light from the ceiling and downlight from sconces which have
a downlight opening). The most obvious answer to this question
is that the top of the sconce should be above eye level so the
interior bulb is not visible. Generally, this would be a minimum of
six feet from the floor. Therefore, the wall box for that sconce
should be six feet less the distance from the top of the sconce to the
center of the wall box. This dimension is found on each sconce page
which has a link for "View Technical Drawing". This
dimension is shown from the bottom of the sconce, so subtract that
amount from the overall height of the sconce.

The
amount of light emitted by the sconce will depend on how close it is
to the ceiling. The closer to the ceiling, the shorter the light path
of reflected light is to the floor. Remember, these sconces provide
ambient light which is a gentle light source suitable for normal
activities short of intensive eye work as in reading or working on
physical objects. Also, of course, the number of sconces affects the
total light available in a room. The human eye is a remarkable
instrument, demanding a lot less light for non-technical tasks, such
as navigating a hallway or dining. This ability to accommodate itself
to available light is called visual acuity and the human eye far
exceeds the photographic process in this matter.
